Thanks to NetGalley and the publisher for the advanced reader copy of Deborah Swift's novel 'Operation Tulip'.

Set in German occupied Northern Holland, British agent Nancy Callaghan is undercover working with the Dutch resistance to gather intelligence regarding the whereabouts of a high profile resistance member who has been captured by the Nazis. Putting herself in extreme danger she assumes the identity of a wealthy Dutch widow and seeks to infiltrate the Nazi SS by becoming close with a high ranking SS member. Back home in England, her boyfriend Tom Lockwood is desperate to bring her home. Devising Operation Tulip, he sets out to locate Nancy. Encountering first hand the brutal hardships faced by the Dutch, Tom finds himself under the control of the Dutch resistance and must bid his time to find Nancy.

An interesting addition to the wealth of WW2 historical fiction on the market. The book contains many interesting historical facts, however I felt overall the book became weighed down by the multiple plot lines and could have benefitted from a punchier ending.
